The dissolution of ammonium nitrate in water is given by the following equation: NH4NO3(s) + heat → NH4+(aq) + NO3-(aq)

Which statement best describes what an energy graph of this reaction would look like?

The reactants would appear at a lower energy state than the products.

The reactants and products would appear at a low energy state.

The reactants and products would appear at a high energy state.

The reactants would appear at a higher energy state than the products.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

did anyone actually do this? like if anyone has submitted this i rly need .
